Application January 4t, 1938, Seriai No. 1832M t Claims.

The invention relates to the fabrication of boxes or containers made from materials of the nature of cardboard, pasteboard, or like fibrous stock, and especially to the fabrication of a top or cover member for such container. More particularly, the invention consists in providing a cover member having a side strip of paper board stock, covered with'a thin sheet of decorative paper, constituting a ring adapted to be assembled with a single sheet bf coardboard constituting the head of the cover member, the assembled top being designed to telescopically engage the open end of the container and to form therewith a completed box.

In its broadest aspect, the present invention consists in forming a bead throughout the upper peripheral edge of the ring constituting the side wall of the cover member, flattening such bead substantially completely so as to form a flange extending inwardly from such side wall member, applying a quantity of glue or other adhesive material to the lower surface of the flange and securing, by means of such adhesive, a single sheet of cardboard constituting the crown or head of. the

a container top, to such side wall.

In the fabrication of a top or cover member for a container of this general type, it has been the practice to form a head of substantially fully rounded form at the upper periphery. of the ring constituting the side wall of the cover, and it was sought to prevent the tendency of such rounded bead to unroll by applying thereto a structure consisting of two sheets of cardboard, one formed with a peripheral groove into which the bead was adapted to fit snugly, and the other, or'bottom member, formed of a single sheet of stock positioned immediately below the first or crown portion, and extending so as to have its peripheral edge abut the portion of the ring member immediately below the rounded bead, thereby maintaining the cover structure in frictional engagement with the inner and lower surfaces of the rounded bead.

We have found that such prior art construction does not, to any appreciable extent, prevent the loosening of the contact between the head of the cover member and its side wall. On the contrary, such a frictional contact, in spite of the snug fit by which it is produced, yields a structure which is not characterized by any particularly efiective'strengthening of the box structure.

By'our'novel construction of container top, we attain a sturdiness and added strength oharacterizing the joint between the elements of the container top, which is not dependent upon any frictional holding of the elements thereof together, but being dependent upon positive adhesive contact between such elements, secure a measure of added strength of the joint, and, therefore, an added sturdiness oi the entire box structure with (or. sac-5.5)

out resort to the use of a lining member in the cover structure, such as has been found necessary in the fabrication, in accordance with the prior art, of similar types of container tops.

In addition to the increased strength, rigidity, and therefore, sturdiness, of the container top structure, our novel construction is characterized by a pleasing appearance of the container, a fea- I ture of considerable importance in the fabrication of fancy boxes which, however, must be capable of being produced at relatively low cost and for competition with more expensively produced boxes.

Our novel structure, therefore, is attractive in appearance, sturdy in structural composition, and may be fabricated at a cost considerably lower than similar boxes of conventional construction.

A specific embodiment of our invention is illustrated in the accompanying drawing, in which Fig. l. is a partial vertical section through a container having a top or covermember in the fabrication of which our novel structure has been embodied; Fig. 2 is a fragmentary vertical sec tion through the ring member constituting the side wall of the container top, showing the formation of the rounded bead at the upper edge thereof; Fig. 3 is a view, in similar section, of

such ring member after the head at the upper edge thereof has been substantially completely,

Referring more particularly to the drawing, in

which similar reference characters identify sirnilar parts in the several views, the body of the container is designated generally as 5, such body having the upper peripheral edge thereof formed with a rounded bead 6. Our invention is concerned not with the structure of the container body, but with. that of the top or cover member, which is constituted of a ring 5 of cardboard, pasteboard or like fibrous material formed, as shown in Fig. 2, with a substantially circular head 8. This bead is then completely flattened so as to have the form of a flange a substantially as shown in Fig. 3, in which the two parts of the flange are in substantial contact at the core it of the flange. i

As shown particularly in Figs. 2 to t, the ring member may be provided with facing layers of paper it, constituting finishing strips which may be suitably ornamented by decorative printing or otherwise.

The crown portion of the container top is con.- stituted of a strip it of cardboard, pasteboard or the like, such strip having ,its peripheral edge portions bent downwardly and outwardlyso as to forms. recess throughout the peripheral edge 7 of the crown portion, in which recess'the flange I it is adapted to be seated.

The assembling of our novel structure of container top, in contra-distinction to the practice of the prior art, is effected by applying a layer ll of glue or other suitable adhesive material to the bottom surface of the flange 9 and pressing the peripheral edge portion of the crown member I! against such adhesive materal so as to eflfect a joining, by such adhesive, of the peripheral edge portion of the crown I2 to the bottom of the flange 9.

The crown member l2 of the cover may advantageously be provided with a surfacing strip l4 carrying the same design or embellishment as does the facing strip 1 l of the side wall of the container top, so as to maintain substantially the same design throughout the outer surface of the completed container cover.

It will be noted that in accordance with our novel construction, as shown clearly in Figs. land 4, the portion of the crown member constituting the side wall forming the recess along its peripheral edge, is not anywhere in contact with the inner edge of the flange 9. By this construction, a particularly attractive appearance of the container stop, with a substantially open ridge I5 throughout its peripheral edge, is produced, such ridge breaking up the continuity of surface produced by the intervals during a period of time usually of conjuncture of the crown and the side wall of the container top.

It will also be noted that the peripheral edge of the crown l2, in the assembly thereof with theside wall of the container top by means of the layer of adhesive i3, is somewhat removed from the inner face of the ring constituting the side wall immediately below the flange 9, there being a clear space l6 between the peripheral edge of the crown l2 and the ring I, so that no pressure is applied by such peripheral edge against the side wall. Thus,

no stresses or strains are possibly produced by hav-' ing an inordinate pressure applied by the peripheral edges of the crown member against the side wall, such as characterize the structures of the prior art and which we have found objectionable as producing a tendency of causing a loosening of the joint betwen the crown member and side wall of the container top. By eliminating all frictional contact between the crown member and the side wall, we are enabled to produce a container top, at low cost, and, not being dependent upon merely frictional holding of the elements thereof together, the strength, sturdiness and, therefore, the life of the container is appreciably increased. This is an important feature in connection with boxes of the general type to which the invention relates, as such boxes are usually used to contain commodities such as candy and powder, which are not removed in toto from the container, but are dispensed therefrom at periodical siderable duration commensurate with the quantity of the supply, of commodity contained in the box.-

While we have described a specific embodiment of our invention, it is obvious that various changes therein, particularly in the arrangement and configuration of the several elements thereof, within the ambit of the claims, may be made without departing from our invention.
